'To all whont it may courier-$1,:

Be it known that I, Janus Annsrnoxo, residing at Baltimore, State ofMaryland, have invented certain new and useful linrovernents inProcesses of lleodorizing Pctroleu1n Distillate; and I do declare thefollowing to be a full, clear, and .xact los -.rip tion of theinvention,- such as will enable others skilled in the art to which itapportains to make and use the same.

My invention relates to a process l or treating petroleum distillate.

It has for its object to deodorize the distillate and bring it to acondition suitable for burning or illuminating purposes, free .fromoffensive or unpleasant odor, and capable of use without forming orleaving a deposit to interfere with the satisfactory function of a lampwick or burner.

To the accomplishment of the foregoing and such other objects as mayhereinafter appear the invention will be hereinafter fully described andthen sought to be clearly d'efined by the claims.

For one illustration of the invention it will be described as applied tothe distillate ob.- tained in the usual way from the petroleum or oilfields of Pennsylvania.

'1 first prepare a solution by dissolving forty (40) pounds ofchlorinated lime in lil'ty gallons of water and allowing it to stand fora period sullicient to permit the insoluble substances to precipitateand deposit in the vessel containingthe solution. For instance, thesolution is usually allowed to stand for a period of from twelve tofourteen hours, or

'thereabout. The liquid is then drawn oil, so as to separate it from theprecipitate. To this liquidis added a solution made by dis solving sixtypounds of carbonate of soda in ten (10) gallons oi water heated to atemperature of about 200 l i-ihrenhcil, and the liquid with the curlonato-of-soda solution added is allowed to stand for a period of twelve(12) or fourteen (14) hours, or there- 4 about, so that the constituentsfor which the carbonate of soda has allinity may be preoipitated.'lhcresull ing liquid is then drawn oil into a separate vessel,separated from the precipitate, the liquid nou' boinp about,lil'tytwqgss) gallons in volume. To this resulting lilp ii'd: is addeda mixture formed by dissolving one-hall 1;) pound of bichromatc ofpotash in one quart of water, and the liquid with this m ore added isfitllljOCilll to a thorough. agitation. The llllXtUlC or solution thusformed and in volume being about lillydu'o (.3!) gallons added to fourbarrels of ion distillate ol' lil'ty-two (52) gallons iaoh. 'ilhcdistilhtto with. the solution or mixture added is then thoroughlyagitated for a period of twenty minutes, or thereabout, by means of asuitable blower or other suitable agitator, and the vessel containingthe distillate covered and the distillate with the added solutionallowed to stand for a period ol twenty-four (24) hours, or there- 'ihevessel is then opened and the :ngilated for a period ol' ten (10) minorlhcroabout, and then allowed to stand uncovered lor a period ol'twenty-four (2%) or l'orlyazigh! (45) hours, or until the oilscpsiirutos from the precipitated matter and becomes clear. Theprecipitate or deposit is now at the lmltonnoll'tlo vissol io a liquidor seiniliquid state and consists oi constituents oi the distillatewhich have been separated. therefrom and deposited in the vessel by theaction of the solution or mixture upon the constituents ol thedistillate l'or which it has allinitv ihis linal precipitate or depositis then drawn oil and leaves the oil in a clear state and demlorized andready for commercnii use.

The byproduct consisting of the deposit made up); the constituents ofthe distillate separated thcrcl roni by the notion ol' the solution ormixture and precipitated l'orms a lnost ullirivnt gciinicide andantiseptic adapted for use in ho pitals and sick-rooms and l'ordisinl'w-ting plzlposi s in general.

oily the employment olthis process there is saving of time and labor,and the oil does not require to be washed, us with soino otlur methods,and, 'l'iu'tlu'rmi i'o,there is no wa t ol' iuaturiul, us the byqiroductforms :1 gornli ride and (lisinl octant nod the oil in its puriilicd anddeodorim-d state is ready for commercial u:-:e.-

While l have mentioned chlorinated lime, carbonate ol soda, andhieliromate ol' potash as the substances from which the solution isnnulin'yet where the encmii'al equivalents of those substances areni'nplo -od to produce l substantially the results given by thesubstances named such equivalents are to be understood as embracedwithin the sec e of,

the invention, and while I have specifie the proportions found to givethe best results, yet variations in the proportions are comprised withinthe scope of the invention. It may also be mentioned that theprecipitate of the chlorinated-lime solution either .alone or mixed withthe precipitate formed after the addition of the carbonat-of-sbdasolution maybe used for disinfecting purposes either as a wash or as acoating for ceilings, walls, and otherwise. f

The right is reserved to file a separate appliationfor the germicide andantiseptic product as a division of this application.

Having described my invention and set forth its merits, what claim isc1. The process .of deodorizing petroleum distillate consistin insubjectin theoil to "a min ature formed 0 a solution 0' bichromate 2.The process ofdeodorizing' petroleum distillate-consisting in'subjectinthe oil to a mixture formed of a solution oi bichrornate ofpotash and asolution formed by de'composing a solution of chlorid of lime by theaddition thereto of a solution of carbonate of soda, substantially intheproportions specified; 3. The process of m a mixture for deod'orizingpetroleum distillate consisting in making a chlorid-of-lime solution andsepa- 7 rating the lit uid from its precipitate; then 35' addingto sailiquid, a'solution'of carbonate of soda, and. then adding to the mixtureof the first two solutions, a solution of bichro-- mate of potash,substantially as described.

4. The process of dreodorizing petroleum-4o distillate consistingin'subjecting the oil, un-

der agitation, to a mixture formed of a solu tion of chlorinated limeand a solution of ear- 5 bonate of soda, and the addition of a solutionof biehromate of potash to the mixture of the chlorinated-lime andcarbonate-of-soda solutions, substantially as described;
